Hsin is the 5-star Electro Rectifier arriving in Wuthering Waves Version 3.7, and she is the game’s first playable Sentinel. Building her from level 1 to a fully leveled kit pulls from enemy drops, a world boss, a weekly boss, Forgery Challenge strings, and one local specialty. Most of those lines are already farmable, so you can bank resources ahead of her banner and finish the build the moment you pull her.
Quick answer: A level 90 Hsin with maxed Forte and her signature weapon needs Autopuppet Kernels, Strings, Exoswarm Cores, Solidarity’s Loneflame x46, Bloom of Hearkening, and Remnant of the Wheel, plus roughly 2,530,000 Shell Credits.
Full Hsin material checklist for level 90 and max Forte
The totals below cover Hsin’s ascension, her complete Forte tree, and her signature Rectifier Blooming Jadehaven combined. If you only plan to raise her character level and skills, subtract the weapon column detailed further down.
| Material | Total needed |
|---|---|
| Shell Credit | 2,530,000 |
| LF Autopuppet Kernel | 29 |
| MF Autopuppet Kernel | 40 |
| HF Autopuppet Kernel | 52 |
| FF Autopuppet Kernel | 61 |
| Solidarity’s Loneflame | 46 |
| Bloom of Hearkening | 60 |
| Remnant of the Wheel | 26 |
| Spliced String | 31 |
| Broken String | 36 |
| Solidified String | 61 |
| Melodic String | 87 |
| LF Exoswarm Core | 6 |
| MF Exoswarm Core | 6 |
| HF Exoswarm Core | 10 |
| FF Exoswarm Core | 12 |
Among all materials in her build, Melodic String has the greatest Forgery cost. It is limited to the upper difficulty tiers, so raise your clear level as much as your account permits before farming in bulk.
Two materials you can’t collect before Version 3.7
Seven of Hsin’s nine material lines sit on live farming routes, but two stay locked until the update goes live on September 30, 2026. Everything else can be pre-farmed now.
- Bloom of Hearkening grows in Mengzhou’s Simulacrum Nexus, the new area made available by Chapter IV Act IV, and counts as a local specialty.
- Remnant of the Wheel drops from the new weekly boss added in Version 3.7, so it cannot be stockpiled ahead of launch.
Where to farm each Hsin material
LF, MF, HF, and FF Autopuppet Kernel
Autopuppet Kernels drop from Autopuppet enemies in Mengzhou, including Porcelain Picket, Kernel Puppet, Stone Picket, and Aureate Picket. You can also track them through Autopuppet Tacet Discords using the in-game material detection. Suisui and Qingxiao share this drop, so any stack you already farmed for them counts toward Hsin.
Three Kernels from a lower tier convert into one from the next tier up. Hsin’s complete build requires 29 LF and 40 MF, so converting all of either tier into FF will leave you needing to farm them again.
Solidarity’s Loneflame
This ascension material comes from the Myriad Snare: Rustfire Chassis world boss in Mengzhou. Suisui ascends on the same drop, so check your inventory before grinding the boss, since part of the 46 may already be in storage.
Bloom of Hearkening
You gather Bloom of Hearkening, a local specialty, in the Simulacrum Nexus of Mengzhou, and the Huaxu Apothecary also sells it. Since the Nexus becomes accessible through the story quest, Chapter IV Act IV—not the banner—is the actual requirement for this item.
Spliced, Broken, Solidified, and Melodic String
Because Hsin wields a Rectifier, her materials come from the String Forgery line. The Lesson in Sunset Forgery Challenge in Etching Plains provides all four rarities, as do other Rectifier Forgery Challenges in Mengzhou. Lahai-Roi Supply Packs and Synthesis are additional sources, while the highest-rarity Strings appear in the upper difficulty tiers.
LF, MF, HF, and FF Exoswarm Core
Exoswarm Cores are only needed for Blooming Jadehaven. They drop from Exoswarm enemies and appear as side loot from Etching Plains Forgery Challenges. You can also use in-game material detection to locate the enemies on the map.
Remnant of the Wheel
Remnant of the Wheel is a Forte upgrade material from the new weekly boss introduced in Version 3.7. With three claims per week, gathering all 26 takes several reset cycles, and the boss only opens on patch day.
Ascension cost from level 1 to 90
Raising Hsin’s character level to the cap uses four items plus Shell Credits. The world boss drop and the local specialty are the two lines here that gate this stage.
| Material | Total needed |
|---|---|
| Shell Credit | 170,000 |
| LF Autopuppet Kernel | 4 |
| MF Autopuppet Kernel | 12 |
| HF Autopuppet Kernel | 12 |
| FF Autopuppet Kernel | 4 |
| Solidarity’s Loneflame | 46 |
| Bloom of Hearkening | 60 |
Forte upgrade cost for a maxed skill tree
Her Forte tree contains Normal Attack, Resonance Skill, Resonance Liberation, Forte Circuit, and both Inherent Skills. At 57 FF Autopuppet Kernels and 67 Melodic Strings, it accounts for the more costly half of her build.
| Material | Total needed |
|---|---|
| Shell Credit | 2,030,000 |
| LF Autopuppet Kernel | 25 |
| MF Autopuppet Kernel | 28 |
| HF Autopuppet Kernel | 40 |
| FF Autopuppet Kernel | 57 |
| Spliced String | 25 |
| Broken String | 28 |
| Solidified String | 55 |
| Melodic String | 67 |
| Remnant of the Wheel | 26 |
Blooming Jadehaven weapon cost
Blooming Jadehaven is Hsin’s 5-star signature Rectifier. Its ascension pulls from Exoswarm Cores and reuses the same String line as her Forte tree, so plan the 20 extra Melodic Strings on top of the 67 her skills need.
| Material | Total needed |
|---|---|
| Shell Credit | 330,000 |
| LF Exoswarm Core | 6 |
| MF Exoswarm Core | 6 |
| HF Exoswarm Core | 10 |
| FF Exoswarm Core | 12 |
| Spliced String | 6 |
| Broken String | 8 |
| Solidified String | 6 |
| Melodic String | 20 |
Once you have every line above, Hsin can reach level 90 with all Forte nodes maxed and her signature weapon leveled in the same pass. Farm the Exoswarm Cores first in Etching Plains, then move the rest of your String runs into Mengzhou, where the domain also drops Autopuppet Kernels and covers the bulk of her needs at once.
